Question

Crude oil is separated into its constituent chemicals through :

• A. Steam distillation
• B. Vacuum distillation
• C. Fractional distillation
• D. Crystallisation

Answer 1

The correct option is C Fractional distillation

Steam Distillation is a separation process for temperature sensitive materials like natural aromatic compounds.

Vacuum distillation is a technique that uses a vacuum to extract analytes from a sample.

Crystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution.

Fractional Distillation is a separation technique that is used for liquids that dissolve in each other. Liquids that dissolve in each other are called miscible. A liquid can be separated from a mixture of liquids in a solution by fractional distillation.
